Consider the following scenario. Use your knowledge about scientific evidence to answer the question that follows.
Concrete, used in sidewalks, is composed of three substances: cement, an aggregate (like sand), and water. When mixed together, these three substances produce a reaction in which calcium ions are formed. The product of this chemical reaction is what is known as concrete. Each time you perform this experiment, you get the same result. Which of the following statements describe the results produced by this experiment?
a. The results provide evidence that rests on an argument from authority.
b. The results provide anecdotal evidence.
c. The results provide empirical evidence derived from observations of the natural world.
d. The results provide evidence that is replicable, or repeatable, in future experiments.

Answers

Answer 1

Answer:

D

Explanation:

If these three substances are mixed together with the required proportion, it would yield concrete all the time. Thus, the result is replicable, or repeatable, in future experiments.

The result is not from an observation of the natural world because the three substances were mixed together by man in a lab.

What factors best explain the the
relative advantage of civilizations in the modern
world and to what extent might that advantage
be rooted in the geographical features of human
civilizations beginnings?

Answers

lThere are many factors that have contributed to the relative advantage of certain civilizations in the modern world. These include a variety of historical, cultural, economic, and technological factors. Some of the key factors that have contributed to the relative advantage of certain civilizations include:

Access to natural resources:

Civilizations with access to abundant natural resources, such as fertile land, minerals, and energy sources, have often been able to leverage these resources to fuel economic growth and development.

Cultural and social institutions:

The values, beliefs, and institutions of a society can play a significant role in its development. Civilizations with strong cultural traditions of innovation and learning, for example, may be more likely to advance technologically and economically.

Political and economic systems:

The political and economic systems of a civilization can also influence its relative advantage. For example, civilizations with more open and inclusive economic systems may be more innovative and better able to adapt to changing circumstances, while those with more closed and centralized systems may be less flexible and adaptable.

Infrastructure:

Access to transportation, communication, and other infrastructure can also play a role in a civilization's relative advantage. Civilizations with well-developed infrastructure may be better able to facilitate trade, communication, and the movement of people and goods, which can contribute to economic growth.

It is difficult to quantify the extent to which the geographical features of a civilization's beginnings might impact its relative advantage in the modern world. However, it is likely that the physical environment has played some role in shaping the trajectory of human civilizations, particularly in terms of access to natural resources and the development of transportation and communication infrastructure.

Which factor led to the development of slavery in both Mesopotamia and Egypt?

Answers

Answer:

Slavery has existed in various forms throughout history, and there have been many different factors that have contributed to its development. In ancient Mesopotamia and Egypt, one factor that led to the development of slavery was the need for labor. Both civilizations were agrarian societies that relied on agriculture for their survival, and they needed a large workforce to cultivate their crops and maintain their irrigation systems.

Although there are no options attached we can say the following.

The three ways how social pressure could be regarded as a stressor for young people in their family relationships ​are the following.

1.- Family pressures young people to behave like someone else. How many times yo have heard parents say "you have to be like your older sister..." "You have to be like your cousin Arthur..."

2.- Fulfill expectations. Your family in general, and ypur parents in specific, set a series of expectations that you are supposed to fulfill. You have to go to class, have good grades, respect family values, attend family events, do what your father/mother wants you to be, and so on.

3.- Behave as other people do in society and trying to fill in those expected social roles. The traditional idea of go to school, get a degree, have a decent job, getting married, have children, be a good Christian, obey the laws, follow orders.

That is why, when some people act in a different way or try to break social rules, everybody questions them. It seems that being different is a sin and people can't stand an individual who tries to be true to himself and his beliefs.

The three ways on how social pressure could be seen as a stressor for young people in their family relationship is that it leads to ​depression, a kind of aggressive behavior in the person and also antisocial behavior.

Suppose that you want to determine whether there is a difference between the distances traveled by an air-filled football and by a helium-filled football, and that you have managed to recruit 12 punters of varying abilities to participate in the study. Describe, in detail, the design of an experiment that does not utilize pairing. Next, describe, in detail, the design of an experiment that does utilize pairing. Which study design (a) or (b) do you think is a better study design for the purpose of this study or does it not matter

Answers

Answer:

a) step 1 : Divide the punters into two equal groups

  step 2 : Punters in each of the group is made to kick the ball ( i.e. Group 1    kicks an air filled football while group 2 kicks helium filled football )

step 3 : measure the average distances that the ball travelled in each group

step 4 : compare the results and draw a conclusion

b)  

Each punter is given both air filled and helium filled footballs

Each punter kicks both the air filled and helium filled footballs

The distances travelled by the balls are recorded ( measured in pairs )

c)  Design B

Explanation:

Given data:

Aim : To determine if there is a difference between distances travelled by an air-filled football and a helium-filled football

An air filled football and a helium-filled football

Number of punters recruited for the test = 12

a) Description of an experiment that does not require pairing

step 1 : Divide the punters into two equal groups

step 2 : Punters in each of the group is made to kick the ball ( i.e. Group 1 kicks an air filled football while group 2 kicks helium filled football )

step 3 : measure the average distances that the ball travelled in each group

step 4 : compare the results and draw a conclusion

b) Description of an experiment that requires pairing

Each punter is given both air filled and helium filled footballs

Each punter kicks both the air filled and helium filled footballs

The distances travelled by the balls are recorded ( measured in pairs )

c) Design B is better because the ability of each punter while kicking the balls are not the same hence there is need to allow each punter kick both balls, also for paired design/experiment.  T-test can be applied

Donny's non-profit organization mailed out small pins with their symbol on them to people in the community two weeks before they went door to door asking for donations. They noticed that the people who had the pins on when they answered their door were more likely to give a donation. An explanation for this, according to social psychologists, would be:

a. Once someone has agreed to give a small donation, they are more likely to give a larger one.
b. Once someone has made a commitment, or taken a position on an issue, they are more likely to make other commitments that are consistent with our first one.
c. Donny is annoying people during dinner by knocking on their doors, so to get rid of them they gave them a donation.

Answers

Answer: b. Once someone has made a commitment, or taken a position on an issue, they are more likely to make other commitments that are consistent with our first one

Explanation:

Social psychology, through the Theory of Reasoned Action and the Theory of Planned Behavior, suggest that personal traits and past behavior can be used to predict future behavior. People who have taken a position in a subject, like those who decided to wear the pin, probably tend to help others and apply their moral responsibility to charitable giving.

Option a. is incorrect because the example doesn´t describe people that have already agreed to give a small donation. Option c. is incorrect because the example doesn´t provide any information about the time Donny was going door to door, so we don´t know if him going at dinner time was a factor.

Once someone has made a commitment, or taken a position on an issue, they are more likely to make other commitments that are consistent with our first one

What is commitment?

The word commitment means agreement made to carry out certain obligations sooner or later. Oftentimes, people who commit to do certain things does so with a promise.
